T
he Finance Ministry has sought to fix software bugs and faulty infrastructure in its new online tax system in time for next year’s filing season to prevent a repeat of the complaints and delays seen this year, which it blamed on the vendor.
Finance Minister Purbaya Yudhi Sadewa said in a media briefing on Friday that the system, called Coretax, would be up and running in January or February, leaving enough time for the annual tax filing deadline of March 31 for individuals and April 30 for corporations.
“The infrastructure is beyond sufficient, very much beyond sufficient, all that is left to do is maximize its usage. The tech that we bought was expensive and sophisticated, but we did not know how to use them, that is more or less what happened; which is okay, we are learning,” said Purbaya.
Initially intended to be fully implemented for this year’s tax filing, the Coretax website proved slow and unstable for many users. It tended to load blank pages and, in many cases, led to failures in issuing tax invoices.
The government and the House of Representatives agreed in mid-February that the full implementation of Coretax be postponed, and the public allowed to use the legacy taxation system. The haphazard implementation was seen as a contributing factor for nosediving tax collection in January and February.

In a previous statement, the minister claimed Coretax could be fixed within a month, but he admitted in Friday’s briefing that this was mistaken, given that it required programming work the ministry could not tackle, due to a contractual clause with the vendor of the system.
